OWC Elektron USB-C SSD

OWC Elektron USB-C SSD

Get OWC Envoy Pro Elektron at, 1TB and 2TB capacities.

Here, MPG assesses the late 2020 OWC Envoy Pro Elektron USB-C SSD, available in 240GB/480GB/1TB/2TB capacities on the 2019 Mac Pro.

The OWC Elektron USB-C SSD is characterized by outstanding performance in an ultra-compact form factor, ultra-durable build quality, bus-power, and totally silent operation.

The OWC Elektron offers consistently high performance across the entire capacity that makes it a far superior choice over competing products like the Samsung T7.

With its ultra-high performance that maxes-out the USB-C bus (see tests that follow), the OWC Envoy Pro Elektron is suitable for Mac or PC and for desktops or laptops.

The laptop usage is clear—and a great way to pocket all your stuff just in case the laptop disappears while traveling—but so compact is the Elektron that one might ponder affixing it in place to the rear of an iMac or Mac Mini with velcro.

One need not have a USB-C port; the Elektron’s supplied cable can be plugged into either a USB-C or USB-A port, for outstanding convenience on older machines, or between differing ones.

Tested: Sustained transfer speed

Performance testing by DiskTester, part of diglloydTools.

Read and write speed across the entire 1TB capacity shows as high a performance level as one might hope for with almost no deviation. This is as good as it gets for USB-C performance, and under a sustained maximal I/O load far exceeding anything resembling normal usage.

Throughput figures are real-world transfer speed through the macOS file system.

Tested: Transfer speed vs transfer size

Even the small 32K I/O sizes hit speeds over 200MB/sec and this doubles by 128K. Typical of all SSDs, transfer size needs to hit 1MiB to 2MiB in order to reach 95% of peak speed.

This is a very strong performance that rapidly approaches the limits of the USB-C bus.

Transfer speed vs transfer size of 1TB OWC Envoy Pro Elektron SSD


The 1TB OWC Envoy Pro Elektron USB-C SSD is a class-leading performer at an attractive price for its capacity and very high build quality. And with a 3-year warranty, OWC stands behind their products three times as long as Apple does.

The OWC Envoy Pro Elektron is the perfect add-on for anyone looking for ultra high performance for any computer with USB-C that is flagging in its internal storage. Being bootable, it is also a highly attractive upgrade for a clone backup of the system volume.

Get the best!

For anyone who really wants the best, the OWC Elektron trounces the Samsung T7 whenever sustained I/O performance is a goal, as the graph shows. The price difference is modest, but the performance difference is huge. And the OWC Elektron is also IP67 water resistance and virtually indestructible vs the Samsung.

Samsung T7 is about $270 @AMAZON. Is $100 for 2nd-rate performance worth it?
